Node-RED prepares the data and sends it to CalcsLive.</li>\n<li><strong>B — JSON inside CalcsLive:</strong> Configure input values and output units in the CalcsLive node, then trigger it with the dashboard button or an Inject node.</li>\n<li><strong>C — Dashboard JSON editor:</strong> Edit the Inputs and Outputs JSON on the dashboard and run the speed calculation.</li>\n<li><strong>D — Choose your article:</strong> Enter a CalcsLive Article ID and its Inputs and Outputs JSON on the dashboard. View the first requested output on a gauge and open the linked article.</li>\n</ul>\n<p class=\"mt-3 mb-0\">CalcsLive accepts upstream values in their original units, handles the calculation and unit conversion, and returns\nresults in the units you request for display or downstream nodes.</p>\n\n<p class=\"mt-3 mb-0\">In other words, you can offload unit conversion and calculation from you flow to CalcsLive and enjoyr full Unit Freedom.</p>\n</div>\n</template>",
